    Asymmetric Reduction of Monoketo Hexadecanoic Acid Methyl Esters
    (Asian Journal Of Chemistry, 2013) Turker, Gulen; Yusufoglu, Ayse
    Methyl 2-,3-,6-,8-,14- and 15-keto hexadecanoates were reduced by using NaBH4 in presence of 1,2;5,6-di-O-isopropilydene-D-glucofuranose [DIPGH], R(+)-1,1'-binaphthyl-2,2'-diol [RBND] and pivalic acid [PA]. The reduction of 2- and 3-keto esters in the presence of (+)-1,1'-binaphthyl-2,2'-diol results in considerably higher stereoselectivities (95 % ee). Enantiometric excess (ee %) was determined by H-1 and C-13 NMR analyses using a shift reagent, Eu(tfc)(3).
